Hi Michal,


Which revision of default.xml are you using?  Adrian thinks it could be potentially related to, and fixed by, this commit[1] if you don't have it yet.

Subject: [seL4] CamkesVM CMA34CR_centos app
 
Hi all,

I have a CM34CR CPU module and I am trying to run the related camkes app on it. 

I choose the centos app: https://github.com/seL4/camkes-vm/blob/master/apps/vm/cma34cr_centos.camkes

I am using default camkes vm manifest from https://github.com/seL4/camkes-vm-manifest.

Compile with:
make clean
make cma34cr_centos_defcondig
make silentoldconfig
make

And then I create a bootable USB following instructions here.

Then after I load the kernel and capdl image, I get the following output on serial:

Boot config: console_port = 0x3f8
Boot config: debug_port = 0x3f8

Any pointers at what is the cause of error here? The machien runs normally with vanilla CentOS so I don't think it is a hardware issue. Also, I am assuming the CMA34CR is identical to the one you have on your side (at least checking the lspci output against the camkes description the memory regions etc seem to match).

Thanks in advance.
